What Is a Basilar Fracture?

A thumb metacarpal base fracture is a fracture that occurs at the base of the thumb metacarpal base and is mostly caused by direct external forces. According to whether the fracture line passes through the wrist and palm joints, it can be divided into two types: fractures that are not open or through joints. Articular fractures are located 1 cm from the base of the thumb metacarpal. Clinically, the thumb is in the adduction position, the abduction, palm movement is limited, and local swelling and tenderness are obvious. ^[1]
